Abstract
The utility model discloses an anti-backflow catheter which comprises a catheter body and an airbag, wherein the airbag is not communicated with the catheter body. One end of the catheter body is provided with a catheter inlet, and the other end of the catheter body is provided with a catheter outlet; the end of the catheter outlet is connected with a catheter connector; the airbag is arranged at one end near to the catheter inlet; a membranous hose is axially arranged inside the catheter body; the end of a urine inlet of the membranous hose is hermetically connected with the inner wall of the catheter body, and the other end of the membranous hose is separated from the catheter body. The anti-backflow catheter has the beneficial effects that the anti-backflow catheter is simple in structure, has less links, effectively prevents urine flowing out of the catheter from backward flowing and is very convenient to flush after being blocked.
Description
Technical field
This utility model relates to a kind of catheter, especially a kind of catheter that can prevent the urine adverse current.
Background technology
Catheter is the pipe of doing with rubber, silica gel or plastic cement, is made up of body, air bag, urine pipe joint.Catheter can be through per urethram inserting bladder so that drainage of urine comes out, after catheter inserts bladder, near the catheter head end have an air bag fixedly catheter stay intravesical, and be difficult for deviating from.
The insider generally acknowledges in the catheter urine adverse current and keeps somewhere in catheter is the one of the main reasons that causes urinary tract infection.Application number is that 201020554873.4 utility model patent discloses a kind of multi-functional regurgitation conductance urinal, comprises urinary bag, is communicated with catheter on the urinary bag; Separated in the catheter; Connect through dropper, and have catheter to put in the dropper, stretch on the catheter in the dropper and be connected with a flexible pipe; The flexible pipe lower end connects to weigh down has a plastic ring, and dropper is provided with flow scale; The catheter of said dropper top is provided with actuator.This urinary bag is utilized the dropper on the catheter, can prevent the urine adverse current in the catheter, but complex structure, and intermediate link is many, and back difficult flushing unimpeded takes place to stop up urinary catheter.
The utility model content
To above-mentioned technical problem, this utility model provides a kind of anti-adverse current catheter, can effectively prevent to flow out the urine adverse current of catheter, and simple in structure, and link is few, also convenient flushing after the obstruction.
In order to solve the problems of the technologies described above, the technical scheme that this utility model adopts is:
A kind of anti-adverse current catheter, comprise body, with the not connected air bag of body; One end of body is provided with the urinary catheter inlet, and the other end is provided with the urinary catheter outlet; The urinary catheter port of export is connected with urine pipe joint; Air bag is arranged near the urinary catheter end that enters the mouth, and the body inner shaft is to being provided with membranaceous flexible pipe; The urine inlet end of described membranaceous flexible pipe is airtight to be connected on the inwall of body, and the other end and body break away from.
As a kind of preferred, the length of membranaceous flexible pipe is 2 times of its diameter.Make it closed easily when not having urine, can be washed open by the tension force of urine again.
As a kind of preferred, the diameter of membranaceous flexible pipe equals the diameter of body.
As a kind of preferred, membranaceous flexible pipe is positioned at the section of cooperation of body and urine pipe joint.Flushing unimpeded when favourable and catheter stops up.
As a kind of preferred, urine pipe joint is a wedge shape.Make more firm more easily with docking of drainage tube.
As further technical scheme, cyclic anti-skidding stricture of vagina is arranged on the urine pipe joint.Prevent to come off when urinary catheter is connected with drainage tube.
Owing to adopted technique scheme, the beneficial effect of this utility model is: simple in structure, intermediate link is few, has increased the seal of catheter, effectively prevents the urine adverse current, gets up also very convenient when stopping up afterflush.
Description of drawings
Fig. 1 is the sketch map of the anti-adverse current catheter of this utility model.
Labelling among the figure: 1 body, 2 air bags, 3 urinary catheters inlet, 4 urine pipe joints, 5 membranaceous flexible pipes, the outlet of 6 urinary catheters, 7 urine inlet ends.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is done detailed explanation.
For the purpose, technical scheme and the advantage that make this utility model is clearer,, this utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation this utility model, and be not used in qualification this utility model.
As shown in Figure 1:
A kind of anti-adverse current catheter, comprise body 1, with the not connected air bag 2 of body 1; One end of body 1 is provided with urinary catheter inlet 3, and the other end is provided with urinary catheter outlet 6; Urinary catheter exports 6 ends and is connected with urine pipe joint 4; Air bag 2 is arranged near urinary catheter 3 one ends that enter the mouth, and body 1 inner shaft is to being provided with membranaceous flexible pipe 5; The urine inlet end 7 of described membranaceous flexible pipe 5 is airtight to be connected on the inwall of body 1, and the other end and body 1 break away from.This membranaceous flexible pipe can be by the thin and material of flexible.
The length of membranaceous flexible pipe 5 is 2 times of its diameter.Make it closed easily when not having urine, can be washed open by the tension force of urine again.If the length of membranaceous flexible pipe 5 is long, the tension force of urine just can't make it open, and influence is urinated; If length is too short, can influence the closure of membranaceous flexible pipe 5 again, influence seal.The diameter of membranaceous flexible pipe 5 preferably equals the diameter of body 1, can 1 work of better fit body.When membranaceous flexible pipe is positioned at the section of cooperation of body and urine pipe joint, help the flushing unimpeded when urinary catheter stops up.Urine pipe joint can be designed as wedge shape, makes more firm more easily with docking of drainage tube.Cyclic anti-skidding stricture of vagina can also be set on urine pipe joint, prevent to come off when urinary catheter is connected with drainage tube.
This utility model is according to fluid mechanics principle; 5 of tubular films allow urine to flow to the urine drainage bag direction from bladder; When no urine flow in the urinary catheter is moving, be in closure state because of losing under the tensile effect; Driving in the wrong direction of the plankton that has stoped the adverse current under the effect of urine other strength such as when the patient body position changes that flow out tubular film and wherein possibly exist increased the seal of urine drainage.
The above is merely the preferred embodiment of this utility model; Not in order to restriction this utility model; Any modification of being done within all spirit and principles at this utility model, be equal to replacement and improvement etc., all should be included within the protection domain of this utility model.
